An anonymous individual dropped off a computer hard drive containing over 100 hours of video depicting a sequence of sexual assaults on women, all of whom appear to be disabled, the Los Angeles County Sheriff’s Department said Thursday.

The footage was shot at several locations, including one that appears to be in a residential care facility.

Investigators are seeking the public’s help in identifying where and when the video was shot, as well as who the suspects are that were captured on tape.

The video is not being released but composite drawings of four of the suspects have been created based on the video footage.

Investigators also hope the individual who dropped off the video will contact them again.

"There is a general recognition that we don't need these military-style weapons in New Zealand, so it's very easy to win cross-party support for this," said Mark Mitchell, who was defense minister in the previous, center-right government and who supports the ban initiated by the center-left-led Labour Party.
